Abstract

BackgroundRadicular cysts are the most frequent odontogenic cysts of the jaws. Radicular cysts arising from the primary teeth are very rare and comprise 0.5% to 3.3% of radicular cysts in both primary and permanent dentitions.Case PresentationIn this paper, we report the clinical, radiographical, and histological characteristics of a radicular cyst associated with a maxillary deciduous first molar. The treatment plan included extraction and enucleation of the cyst under local anesthesia after the elevation of a mucoperiosteal flap, which led to satisfactory and uneventful healing.ConclusionEarly diagnosis of radicular cysts associated with the primary dentition allows for a less aggressive treatment plan and prevents adverse effects on the permanent successor.

Case Report:In this paper, we report the clinical, radiographical, and histological characteristics of a radicular cyst associated with a maxillary deciduous first molar
Toxins that exit from the apex of the tooth cause periapical inflammation, which stimulates the epithelial rests of Malassez in the apical periodontal ligament (PDL) and causes the formation of a periapical granuloma

Summary

Introduction

Periapical cysts, which are associated with nonvital teeth, are the most common inflammatory odontogenic cysts. Radicular Cyst Associated with a Maxillary Deciduous First Molar: permanent teeth spontaneously align in their normal position.[5] Some periapical cysts have been reported in association with the primary teeth but those arising from untreated maxillary primary teeth are very rare.[5,6]. The periapical radiograph revealed a well-defined unilocular radiolucency involving the periradicular area of the primary canine and the first primary molar as well as the developing first premolar (Figure 2). According to the intraoral examination, a well-circumscribed swelling was noticed in the right upper buccal sulcus, extending from the distal aspect of the primary canine to the mesial aspect of the second primary molar. A round radiolucent unilocular lesion with smooth and well-defined borders in the periapical area of the maxillary right primary canine and first primary molar was observed in the panoramic radiograph (Figure 4).
